Electrostatic Discharge (ESD) Damage Prevention
Anyone who handles ESD-sensitive components must be aware of the damage that ESD
can cause to electronic components and must take the proper precautions to prevent it.
Also, anyone who performs maintenance on Sun StorageTek equipment must complete
an ESD-basics course.
CAUTION:
Potential damage to equipment: Handle ESD-sensitive components only
under ESD-protected conditions. To meet this requirement, always use
the Field Service Grounding Kit (PN 4711) and always follow these ESD
precautions and procedures when you are servicing Sun StorageTek
equipment or handling ESD-sensitive components.
ESD Precautions
Always take the following general precautions when you work with ESD-sensitive
components:
• Wear ESD protection whenever you install, remove, maintain, or repair Sun
StorageTek equipment.
• Keep ESD-sensitive printed-circuit components in their ESD-protective packages
until you have taken all ESD-preventive steps and you are ready to install the
component.
• Do not allow anyone to touch or handle an unprotected ESD-sensitive component
unless that person has taken all ESD precautions.
• Reinstall all equipment covers and close all equipment doors after you have
completed the work.
• If the grounding-kit work surface has been exposed to temperatures above 66ºC
(150ºF) or below 4.5ºC (40ºF), acclimate the work surface to room temperature
before you unroll it.
• Immediately place any component that you have removed into an ESD-protective
package.
• Keep the grounding-kit work surface clean.
Note: To clean the work surface, use a mild detergent and water, and make sure
that the surface is completely dry before you use it.
• Periodically check the electrical resistance of the ground cord and the wrist-strap coil
cord.
Note: The ground cord should measure less than 1.2 M
Ω,
and the coil cord
should measure between 0.8 and 1.2 M
Ω
. Repair or replace the cords if they
no longer meet these requirements.
